Ngữ pháp môn Tiếng Anh Lớp 8 - Statements

Statements
If we want to say what other people said, thought or felt, we can use the direct and indirect speech (reported speech).
The direct speech: "I like it," he said. "Irene is late," he thought. "I will pass the exam," she hoped.
The reported speech: He said he liked it. He thought that Irene was late. She hoped she would pass the exam.
The reported speech is typically introduced by verbs such as say, tell, admit, complain, explain, remind, reply, think, hope, offer, refuse etc. in the past tense.
He said (that) he didn't want it.
She explained that she had been at the seaside.
If these verbs are in the past tense, we change the following:
a) verb tenses and verb forms
b) pronouns
c) the adverbs of time and place
A) Verb tenses
We change the tenses in the following way:
Present - past
"I never understand you," she told me. - She told me she never understood me.
"We are doing exercises," he explained. - He explained that they were doing exercises.
Present perfect - past perfect
"I have broken the window," he admitted. - He admitted that he had broken the window.
"I have been waiting since the morning," he complained. - He complained that he had been waiting since the morning.
Past - past perfect
"She went to Rome," I thought. - I thought that she had gone to Rome.
"He was thinking of buying a new car," she said. - She said he had been thinking of buying a new car.
Will - conditional
Will changes into the conditional.
I will come on Sunday," he reminded me. - He reminded me that he would come on Sunday.
As you can see, both the past tense and the present perfect change into the past perfect.

"I shall appreciate it," he said. - He said he would appreciate it.
2. I should, we should usually change into would.

The verb forms remain the same in the following cases:

We must change it, however, in the following sentence, otherwise it will not be clear whether we are talking about the present or past feelings.
"I hated her," he said. - He said he had hated her.
We do not usually change the modal verbs must and needn't. But must can become had to or would have to and needn't can become didn't have to or wouldn't have to if we want to express an obligation.
Would/wouldn't have to are used to talk about future obligations.

"I needn't be at school today." - He said he needn't be/didn't have to be at school that day.

B) Pronouns
We have to change the pronouns to keep the same meaning of a sentence.

"They called us," he said. - He said they had called them.
"I like your jeans," she said. - She said she liked my jeans.
"I can lend you my car," he said. - He said he could lend me his car.
Sometimes we have to use a noun instead of a pronoun, otherwise the new sentence is confusing.
"He killed them," Kevin said. - Kevin said that the man had killed them.
If we only make mechanical changes (Kevin said he had killed them), the new sentence can have a different meaning - Kevin himself killed them.
This and these are usually substituted.
"They will finish it this year," he said. - He said they would finish it that year.
"I brought you this book," she said. - She said she had brought me the book.
"We want these flowers," they said. - They said they wanted the flowers.
C) Time and place
Let's suppose that we talked to our friend Mary on Friday. And she said: "Greg came yesterday."  It means that Greg came on Thursday. If we report Mary's sentence on Sunday, we have to do the following:
Mary: "Greg came yesterday." - Mary said that Greg had come the day before.
If we say: Mary said Greg had come yesterday, it is not correct, because it means that he came on Saturday.
The time expressions change as follows.
today - that day, tomorrow - the next day/the following day, the day after tomorrow - in two days' time, yesterday - the day before, the day before yesterday - two days before, next week/month - the following week/month, last week/month - the previous week/month, a year ago - a year before/the previous year
Bill: "She will leave tomorrow." - Bill said she would leave the next day.
Sam: "She arrived last week." - Sam said she had arrived the previous week.
Julie: "He moved a year ago." - Julie said he had moved a year before.
Note
If something is said and reported at the same time, the time expressions can remain the same.
"I will go on holiday tomorrow," he told me today. - He told me today he would go on holiday tomorrow.
"We painted the hall last weekend," she told me this week. - She told me this week they had painted the hall last weekend.
On the other hand, if something is reported later, the time expressions are different in the reported speech.
Last week Jim said: "I'm playing next week."
If we say his sentence a week later, we will say:
Jim said he was playing this week.
Here usually becomes there. But sometimes we make different adjustments.
At school: "I'll be here at 10 o'clock," he said. - He said he would be there at 10 o'clock.
In Baker Street: "We'll meet here." - He said they would meet in Baker Street.
Reported questions
Direct questions become indirect-questions with the same word order as statements. The reporting verb say changes into ask, want to know, wonder...
"Where have you been?" he said. - He asked me where I had been.
"What time did it start?" he said. - He wanted to know what time it had started.
"Why won't he do it?" she said. - She wondered why he wouldn't do it.
In yes/no questions we use if or whether in questions. If is more common and whether is more formal.

"Did he marry Sue?" she said. - She wondered if/whether he had married Sue.
Reported commands, requests and advice
The commands, requests and advice mostly have the same form in English: verb + object + infinitive (advise, ask, beg, forbid, order, persuade, recommend, tell, urge, warn etc.).
In the direct speech we do not mention the person in the imperative. In the reported speech the person addressed must be mentioned.
"Get up!" he said. - He told me to get up.
"Please, revise for the test," he said. - He urged me to revise for the test.
"Put on your coat," I said. - I advised him to put on his coat.
Negative commands, requests and advice are made by verb + object + not + infinitive.

Tell can introduce statements, commands, requests or advice. The form is different, however.

Commands, requests or advice with tell
"Leave the room," he told John. - He told John to leave the room.
